I'm Aritra, your go-to person for shipping products end to end!
I'm a software engineer from Kolkata, India — currently building a venue operations platform alongside two working industry engineers, where I own the business dashboard: real-time messaging, presence and a Canvas floor-plan editor running in production.
I'm pursuing a B.E. in Information Technology at Jadavpur University (CGPA 8.34, class of 2027). I work across the stack — React, Next.js and TypeScript up front; Node.js, PostgreSQL, Redis and Docker behind — with side quests into React Native and AI-powered pipelines.
A competitive programmer at heart: LeetCode Knight (top ~5% globally), Codeforces Specialist, and a national olympiad qualifier in both math and physics. When I'm not coding, I'm probably solving problems anyway.
